One object ofthe invention is to provide a container for a'package offrozen carbon dioxide so constructed that gas escaping through an outletin its-top mayzpass off to the atmosphere above the normal water line ofa cooler and thereby prevent water from entering the container.

Another object of the invention is to provide the container with acover-whichmay' be very easily applied or removed and having means atits upper end wherebythe container may be easily lifted from a watercooler for insertion of a new package of carbon dioxide without itbeingnecessary for the operator to dip his hands into the'waterorlthrusta fishing implement downwardly'into-the water in order toengage the container andiremoveit. Another'object of the invention is toso form the cover of the container that'if'placed in a crock over whichan inverted water hot; tle is supported with the neck jofthe bottleextending into the crockit will not be liable to strike the neck of thebottle and interfere with proper seating of the bottle.

The cap '7 applied to' the rece ptacle 1 is of an elongatedconical formation and o'f'such'heightithat'whe-n the receptacle rates, it may escape to' theatmosphere above the water in the cooler andthere'will be no danger ofwater passing through: the cap and 7 into the receptacle. Thereceptacles2 and 3 have been shown supported infan. elevated position above thebottom -ofithe 'co'oleri'b y is resting upon the bottom of the coolerthe means of a convenientfsupport' '8 which:may

be perforated or of an. open-work construction so that water may 'passthrough it' for contact with the 'walls' of the ce tacles-1 d inc thecaps 9 and 10 of these receptacles are shorter than the cap 7. The cap 9has a short conical upper portion '11 which projects which projectsabove the water line.

above the normal water line of the cooler and the cap 10 has itstaperedor conical, upper portion. 12 terminating in a short neck 13 The support14 for the receptacle or container .4;

is of greater heightthan the supports 8 but similarly constructed, "andin this form of the invention the upper end of the receptacle extendsslightly above the water line andthe cap 15 is formed with a flat top orhead'in the center of whichis formed an outlet opening. In each instancea collar 16 is provided about the outlet opening of the cap to reinforcethis portion thereof and to this collar is attached a'ring or eye 17adapted to be grasped .by the-operator'when removing an empty container.or setting a filled one in place. Itwill thus be seen that in each in-.stance thecontainer may be removed orset in place without the operatordipping his hand into the water or. thrusting a rod or the like having ahook at. itsend downwardly into thewater in order toengage the ring anddraw the container upwardly. V InFigure 2, there has been shown an en- Ilargedview of the container, indicated by the numeral l'in Figure 1.Referring to this figure, it ,will be seen that the receptacle or bodyis formed with circumferentially extending corrugations which projectoutwardlybut could project inwardly or extend vertically, as previouslyexplained." This receptacleisopen at its top and adjacent its upper endis formed with anoutstanding circumferentially extending collar 18constituting an angular ledge upon-which is disposed a sealing gasket 19and at diametrically opposite sides of the body carrying depending hooks20. These hooks extend .towardeach other beneath theflange or collar butterminate in spaced relation to each other. 'The top or cap 7 of thereceptacle has its lower cylindrical. portion 21 of such diameter thatthe threads of the receptacle. It will thus be seen that when the capisscrewed tightly into.

place pressure :will'gbe applied to the gasket and a water-tight sealprovided between the cap and body or receptacle. Therefore, thecontainer may be immersed in Iwateri when placed in a cooler.- and;while gas mayescape through the outltopening24 at the upper end of thecap: water will'be. prevented from sweeping intothe; receptacle; Thecollar. 16

may be formed integral with the upper end of the cap or formed separateand'rigidly fixed thereto in any desired manner and the ring preferably.consists ofa metal strand bent; to assume the desired shape and havingits ends passed through the collar and formed v withih'eads at vtheirends. When the cap is appliedit must; be tightly screwed into place, andin orderto allow a spanner wrench to be engaged with the cap fortightening or loosening it there "has been provided a lug 25 forengagement by the wrench and lugs 26 spaced from each other about thecap to engage upper. and lower faces of the Wrench iaw and retain thejaw of. the wrench in proper engagement with the lug 25 when in .us'ewThe container shown in Figure 4 corresponds to the one indicated by thenumeral4 in- Figure 1 and: this container is similar in construction tothat shown in Figure 2, except that its. body portion or receptacle 5has 7 not been shown corrugated, although it may be corrugated if sodesired and its cap or top 15 is, formed with a flat head instead of atapered or tconical upper portion; The head of thecap15 is formed with acentrally lo- 1 cated outlet opening and the collar 16 carrying the ringor eye 17 is secured flat upon the head of the cap about theoutletopening. The cap 15 is threaded upon the upperend of thereceptacle the same as the cap'shownin Figure 2 and the only differencebetween'this cap and the cap shownin Figure 2 residesin thefact thatthiscap is formed with a fiat head orupper wall instead of being ta ered.The receptacle is further provided wit sets of hooks 20'corresponding tothose'show'n in Figure 2-so that the receptacle may. be disposed inaholderand held stationary so that the capimay be screwed tightly'intoplace or removed. V

. The holder on standby: means of which the receptacles are to beheldstationary while applying .or removing the caps. is illustrated inFigures 4 and 5 and consists of acylindrical-body 27 which tapersupwardly and at its lower end is formed with a base 28'wl1ich closes itslower end and is of;such diameter that itiprojects beyond the stand;Openings 29 are formed in the projecting; marginal] portions oftheibase'so that fasteners may be passed through it in order to securethe base .upon atableor other support. From the fupperendof the standproject lugs 80 which extend inwardly and are positioned indiametrically opposed relation to each other. These lugs are ofs'uchthicknessthat they may'pass between the companion hooks 20 of" eachsetof hooks extending downwardly from the ledge'18 of the receptacle andare also of such dimensionsthat after the receptacle has been set intothe standwith the lugs disposed between thefaci-ng hooks it may beturned in order to dispose the lugs between the ledge and thebil1.;of;one hook of tween the container shown in this figure and thatof Figure 2 resides in the fact that the tapered upper portion 31 of thecover or cap slopes towards one side instead of being of a true conicalform. Therefore, the outlet opening formed in the upper end of the capis disposed above a side portion of the receptacle and when thiscontainer is disposed within a crock 32 of the type used in coolershaving a water bottle supported in an in verted position with its neck33 extending downwardly into the crock the upper end of the cap will bedisposed between the neck of the bottle and the walls of the crock whereit will be out of the way and not be liable to be struck by the neck ofthe bottle or interfere with passage of water out of the bottle into thecrock. A collar 34, corresponding to the collar 16, is disposed aboutthe upper end of i the cap and carries a ring'or eye 35, correspondingto the ring 17, and by means of which the container may be easily set inplace or removed. The collar notonly serves as a carrier for'the ring oreye but also constitutes a reinforcement disposed about the upper end ofthe tapered portion of the cap through which the outlet opening forgasis provided and prevents this portionof the cap being liable to be bentand the outlet opening closed if the caps are not carefully handled. Therings 17 and 35 may have chains or equ1valent flexible members connectedto them for engagement with a hook or other overhead support and therebyallow the containers to be suspended in a cooler and lowered as thewater is drawn out of the same or the eye directly engaged with theoverhead support;
